Practice ended about 20 minutes later for the offense than Seattle's defense. That's because coach Mike Holmgren kept the offense around to work on a screen pass, which the team struggled to execute during the team portion of practice.

Tackles Ray Willis and Walter Jones weren't on the field for the afternoon portion, but that's been standard as they are among the players recovering from offseason surgery. With Sean Locklear out with a knee injury, Seattle was left with two tackles participating in Tuesday's afternoon practice: Kyle Williams and Floyd Womack.

Matt Hasselbeck was not on the field for the workout after leaving the morning practice when his back tightened up.

Matt Hasselbeck left the practice field on Tuesday morning with tightness in his back. He went into the locker room and did not return for the rest of practice. That left Charlie Frye the quarterback taking repetitions with the first team because Seneca Wallace is still out with an injured groin.

Defensive end Lawrence Jackson is now working with the first-unit defense and that left him going against that Walter Jones guy who works like the witness protection program at left tackle. He can make people vanish without a trace.

Jones doesn't say much when he works. In fact, Bryce Fisher once said that the most frustrating thing about going against Jones is that he would work his absolute hardest, even to the point he would feel a little fatigued only to see that Jones was barely sweating.

Well, Jackson is getting a similar introduction as the Big Walt remains mostly silent even at practice.

"I'll get a laugh every once in a while," Jackson said. "To him, he's going out there getting his work done and I'm fighting, trying to beat him."
